  • Establishing an Advanced Mexican Gravity Standardization Base
    This joint research project serves for following main scientific objectives: a) supporting the realization of a state of the art national gravity standard in Mexico fulfilling highest accuracy demands in metrology, b) supporting the establishment of a base for a national reference frame for geo-scientific purposes, c) supporting the improvement of a global gravity potential field model for fundamental research in earth science

  • Traceability of the FG5X-220 to the SI units
    The Micro-g LaCoste FG5 is a free-fall gravimeter with a laser interferometer in Mach-Zehnder configuration which uses simultaneous time and distance measurements to calculate the absolute value of g. The instrument itself contains the necessary standards, a rubidium oscillator and a He-Ne Laser, and operates independent of external references. These internal standards need regular comparisons.
